Weight problem

Recently I’ve been getting tired easily from walking. Today, first, I walked my dog after breakfast. Then I went to Harajuku to meet my friend and walked around. After my return home, I walked my dog again. So when I got home, I was too exhausted to do anything. Why have I been so tired? I know the reason. I’ve gained weight! I reached the weight I must not reach and I'm not losing it. Oh my God! I really have to try to lose weight. And yet I ate a bag of Kappa-ebisen alone as I watched TV. What on earth did I do? The problem is that there are some snacks in my house. I try not to buy snacks but my husband buys them for a midnight snack. Yeah, my husband is overweight! He always says that he wants to lose weight, but he never stops buying snacks. Once I threw away all the snacks that he had bought, but he started to buy them again after a while. What can I do to make him stop doing it? Oh, there’s another fat guy in my family. It’s my dog. He reached over eleven kilograms even though his vet recommended that I keep him under ten kilograms. Umm, we all have a weight problem! What will I do? It will be hard but I should try to be a good example by losing weight.
